I had not thought of the cooking oil. I take it you guys prefer it to WD40 or a similar spray?
Does it affect the wood differently?
Makes it taste a lot better

Sorry, Just had to say it.
I think it stays on the blade better but WD-40 was the only other lub I tried. I think you could mixing bar oil with kerosene or diesel (50-50) and use a spray bottle to apply it. Might be worth a try.
Have you had a chance use the ripsaw yet? Be patient, there's a learning curve but it's worth it.
